Definitions
- the present invention relates to a component insert with a sealing plug, which can be formed in at least one flowable, curable material or in a soakable with this fiber material. Furthermore, the present invention relates to a sealing plug for insertion into the component insert and further a method for molding of the component insert in the at least one flowable aushär bare material or in a soakable with this fiber material.
- flowable, hardenable materials include, for example, synthetic resins, plastics or metals, such as low-melting metallic cast alloys.
- flowable, curable materials such as synthetic resins, glues or adhesives, in order to produce a fiber composite material in this way.
- DE 10 14 938 proposes to profile the cross section of the adjacent turns of the wire thread insert such that they form a positive and thus sealing connection in the form of a wire threaded bushing.
- Wire thread inserts with this design are complex and therefore expensive to manufacture.
- CH 251 484 proposes to provide a wire thread insert on its radially outer side with a sealing layer. This layer is intended to prevent a liquid material from getting inside the wire thread insert.
- EP 1 046 446 B1 describes a method in which a helically wound wire is formed into liquid metal under axial compression.
- the axial compression has the goal that the adjacent turns of the wire coil sealingly abut each other. Only when this state is reached, liquid metal is transported into the vicinity of the wire helix, so that according to the mold cavity, a metal part can be formed. Since even with manufactured with small tolerances wire helixes of a certain leakage in their compressed coils is assumed, the method described here is associated with a high reject rate.
- the fixation pin has two opposing mounting ends that facilitate threading the nutplate with liner sleeve and nut onto the fixation pin.
- the fixation pin has two radially expanded regions, between which a radially tapered region is arranged. By placing the nut between the radially expanded portions, the interior of the nut is sealed against the ingress of adhesive. After applying adhesive, use the fixation pin to pull the entire nut assembly against the mounting surface until the adhesive has set. Thereafter, the fixation pin can be removed from the nut by being pulled out against the insertion direction from the nut at its mounting end. In this case, one of the radially expanded areas is overcome.
- Such a Fixation pin is due to its construction and the method disclosed herein only for mounting assemblies on a surface.
- a component insert with a sealing plug according to independent claim 1 discloses a sealing plug according to the independent claim 9 and a method for molding a component insert with such a sealing plug in at least one flowable, curable material or in this impregnable fiber material in independent claim 15.
- the component insert according to the invention comprises a sealing plug, so that the component insert with sealing plug can be formed in at least one flowable, hardenable material or in a fiber material impregnated therewith, an inside of the component insert being kept free of the material.
- the sealing plug has the following features: a cylinder-like sealing body with a radially outer side which is adaptable to the inside of the component insert, wherein the sealing plug has at least one removable mounting aid at a closed end of the sealing body, so that the sealing plug can be used with leading mounting aid in the component insert.
- the present invention comprises known component inserts which are combined with a sealing plug according to the invention.
- component inserts include, for example, wire thread inserts or threaded inserts made of solid material.
- the component inserts characterized by. that they have a passage opening and / or perforated side walls and / or a shell opening, which could fill in a thermoforming process in a curable material or in a combination of materials with this curable material. Since such filling of the openings in the component insert would be disadvantageous, the sealing plug prevents the flowable, curable material from reaching the inside of the component insert.
- the cylinder-like sealing body of the sealing plug is inserted into the interior of the component insert using the mounting aid. Since the cylinder-like sealing body is preferably adapted in its shape to the inner opening of the component insert, the radial outer side of the cylinder-like sealing body sets itself on the radial inner side of the component insert due to its elasticity. If the sealing body does not create itself on the inside of the component insert, it is alternatively also preferred to expand the sealing body within the component insert.
- the sealing plug is further distinguished by its removable mounting aid, with the help of which you can pull the sealing body into the interior of the component insert. So that the mounting aid does not hinder the production of the component with component insert, it is of the sealing body, and thus of the entire sealing plug, removable. It is also preferred to leave the mounting aid on the sealing body, provided that it can be formed in the surrounding material of the component insert or wire thread insert.
- the sealing body comprises at the end facing away from the mounting aid a radially encircling sealing lip and / or an end-face sealing surface.
- An end-face sealing surface can be realized for example by a sealing body in the form of a solid cylinder. It is also conceivable to provide the sealing body as a truncated cone. In addition to this or when the sealing plug is provided as a hollow body, one end of the sealing body is preferably provided with the radially encircling sealing lip. This sealing lip projects radially outward from the sealing body and preferably engages it at the end of the component insert. In this way, a sealing function for the area between the inside of the sealing body and sealing plug is also realized.
- the mounting aid in the form of a rod-shaped or cone-shaped extension. This extends in the axial direction of the sealing body and, relative to the axis of symmetry of the sealing body, arranged eccentrically.
- the wire thread insert to be formed has a pin projecting radially inwards. This pin partially blocks the lower passage opening of the wire thread insert, so that only an eccentrically arranged web or pin can be threaded as an assembly aid through this partially blocked opening.
- With the mounting aid is again ensured that the sealing plug has a tight fit within the component insert or wire thread insert and also the interior of the component insert, based on the length of the component insert, completely fills.
- the mounting aid has a taper adjacent to the sealing body, so that the mounting aid is removable from the sealing body. It has already been mentioned above that the mounting aid ensures a reliable positioning of the sealing plug inside the component insert.
- the mounting aid is preferably removed from the sealing plug prior to the molding process.
- the mounting aid on a predetermined breaking point or separation point, which supports the removal of the mounting aid from the sealing plug. This separation point represents, for example, a taper of the mounting aid, so that it is detachable from the sealing plug by a sufficient tensile force in the axial direction of the mounting aid. It is also preferred to unscrew the mounting aid from the sealing plug.
- the mounting aid may preferably have cuts at which the mounting aid detaches from the sealing body.
- the sealing body has a hollow cylindrical shape, in which an inner opening can be adapted to a core pin of a mold, so that the hollow cylindrical sealing body can be radially expanded via the core pin in the inner opening of the component insert.
- the sealing body in its axial direction is at least as long as the component insert.
- the sealing body is preferably adapted to the depth of the inner opening of the component insert, so that the sealing body after insertion in the component insert covers the entire inner surface of the component insert and thus closes against the penetration of the curable, flowable material.
- the component insert is a wire thread insert or a threaded insert with through-hole and / or perforated side walls and / or shell openings.
- the wire thread Set is formed according to an embodiment of the present invention as a wire bushing.
- the helices of the wire sleeve are wound adjacent to each other to form a largely closed radial outer wall.
- such spirally wound coils of the wire bushing are preferably wound in the geometry of a standard thread.
- other threaded elements such as screws, can be screwed directly into the wire bushing.
- it is not necessary that the wire thread insert is fitted into a preformed thread in order then to adopt the appropriate thread form and be combined with male threaded elements.
- the radial outer side of the sealing body is elastically adaptable to the internal thread of the wire thread insert or the threaded insert or that the radial outer side of the sealing body comprises a structured shape which is adapted to the internal thread of the component insert.
- the radial outer side of the sealing body for example, with a matching to the radial inside of the wire thread insert or the threaded insert threads so that sealing body and wire thread insert or threaded insert form a positive connection.
- the sealing plug comprises only one assembly aid.
- the sealing body has, in addition to the first mounting aid, a second mounting aid, which extends in the axial direction opposite to the first mounting aid from the sealing body.
- first and second mounting aids it is preferable to set the first mounting aid and the second mounting aid in opposite directions under tension during installation of the sealing plug into the component insert, and then install the sealing plug in the component insert. Due to the opposite tensile stresses on the first and second mounting aid of the sealing body in stretched in its axial direction and thus also radially tapered. This facilitates insertion into the inner opening of the component insert.
- the first mounting aid and the second mounting aid are relieved, and the sealing body expands in the radial direction.
- the present invention also discloses the sealing plug according to the invention already discussed above for use in a component insert.
- This sealing plug has the following features: a cylinder-like sealing body having a radial outer side which is adaptable to a radial inner side of the component insert, wherein the sealing plug has a removable mounting aid at a closed end of the sealing body, so that the sealing plug with anticipatory mounting aid in the component insert can be used.
- the present invention discloses a method for molding a component insert into at least one flowable, curable material or into a fiber material impregnated therewith.
- the inventive method comprises the following steps: sealing the component insert with a sealing plug consisting of a sealing body and a mounting aid by inserting the sealing body with anticipatory, removable mounting aid in the component insert holding the sealed component insert with sealing plug at a predetermined location at least partially surrounding the component insert with sealing plugs with the flowable, curable material or with a fiber material impregnated therewith and curing of the material and removal of the sealing plug from the component insert.
- the component insert is first positioned at a predetermined location with or without sealing plug. If the component insert has been positioned without a sealing plug, the sealing plug is subsequently installed in the component insert. If the component insert has already been positioned in a mold or the like, the component insert is now held with sealing plug at the predetermined location. It is also preferable to provide the component insert outside of a mold or away from the location of further processing with the sealing plug. Thereafter, the component insert is then positioned and held at a predetermined location with sealing plug at the location of further processing. According to a further preferred embodiment of the method, the component insert is formed with sealing plugs with or without mounting aid. Thus, according to a method alternative, the mounting aid is removed prior to molding of the component insert.
- the mounting aid on the sealing body.
- the second mounting aid is preferably arranged on the open side of the component insert, the second mounting aid does not have to be removed from the sealing body, but can be used for later removal of the sealing plug from the component insert.
- the sealing plug with an internally hollow, preferably hollow cylindrical, sealing body. Due to this hollow shape of the sealing body, the sealing plug with component insert can be positioned on a core pin and held there while it is molded into the surrounding material. By attaching the sealing body to the core pin of the sealing body is widened in the radial direction. This radial widening causes the sealing body to bear against the inside of the component insert and thus prevents penetration of the flowable, curable material into the interior of the component insert.
- the core pin preferably has a shape adapted to the interior of the component insert in order to expand the sealing plug appropriately.
- This supplied medium widens the sealing body radially, so that likewise the sealing body bears sealingly against the inside of the component insert.

- Sealing plug with mounting aid and 12 shows a flow chart of a preferred embodiment of a molding process of the component insert with sealing plug into a flowable, hardenable material or a fabric or fiber material impregnated therewith.
- Figures 5 and 6 show preferred embodiments of a component insert 50; 60 with a sealing plug 1.
- This assembly is adapted to be placed in at least one flowable, curable material, such as synthetic resins, plastics, metals, low melting cast alloys, or in a woven or fibrous material impregnated with such a flowable, curable material to be attached.
- the erfmdungsfelde sealing plug 1 prevented by its positioning in the component insert 50; 60, that the flowable, curable material into the interior of the component insert 50; 60 penetrates.
- An example of such a component insert is a wire thread insert as shown at reference numeral 50.
- the wire thread insert 50 has mutually adjacent but not necessarily tightly fitting turns. Placing the wire thread insert 50 in a mold to mold it into a flowable, curable material or fabric or fiber impregnated therewith, then between the turns of the wire thread insert 50, the flowable, curable material could enter the interior of the wire thread insert 50. If inside the wire thread insert 50, the flowable material cures, thereby an internal thread of the wire thread insert 50 is glued and unusable.
- FIGS. 5, 7 and 8 A preferred embodiment of the wire thread insert 50 is illustrated in FIGS. 5, 7 and 8.
- the turns of the wire thread insert are wound adjacent to each other, so that they form a threaded bushing.
- This threaded bush is shown in Figures 5, 7, 8 with a sealing plug 10, which is explained in more detail below.
- the radial, preferably cylindrical, outer wall of the threaded bushing 50 forming the turns must not be liquid-tight.
- the inner wall of the threaded bushing 50 preferably forms a standard thread, so that a male threaded element 50 without further adaptation of the threaded bushing can be screwed.
- the inner wall of the threaded bushing 50 provides any desired threads in coordination with a male threaded element (not shown) to be screwed in.
- the flowable, curable material can penetrate into the interior of the component insert 60 via end or side openings.
- Such component inserts 60 include threaded inserts, connection inserts that provide a keyhole or structure for a bayonet lock or the like.
- Another example is sockets for electrical or mechanical connectors.
- such a component insert 60 is shown in FIG. 6.
- the component insert 50; 60 With frontal and / or lateral openings in a flowable, curable material or a tissue or fiber material impregnated therewith, the component insert 50; 60 closed with a sealing plug 1.
- the present invention will be described with reference to the wire thread insert 50.
- the wire thread insert 50 consists of a plurality of turns arranged one above the other in the axial direction, which abut each other in a nearly sealing or non-sealing manner.
- the wire thread insert 50 has a widened insertion opening 52.
- the wire thread insert 50 has a further end opening 54. Since the wire thread insert 50 has a radially inwardly projecting pin 56, the frontal opening 54 is arranged eccentrically. Without pin 56, the frontal opening 54 would be centrally located. With respect to other component inserts 60, it is also preferred that these also have an end opening 64 that is centrally or eccentrically located.
- the inventively preferred sealing plug 1 for the wire thread insert 50 is shown in Figures 1 and 2 alone and in Fig. 5 in combination with the wire thread insert 50.
- the sealing plug 1 according to the invention consists of an elastic and resistant to mechanical and chemical attack material, such as elastomeric materials and silicones.
- Other preferred materials for the sealing plug 10 are thermoplastic rubber, silicone rubber, high temperature flexible PVC, or ethylene-propylene-diem (EPDM) rubber.
- the sealing plug 1 consists of a sealing body 10 with optional sealing lip 12 and a mounting aid 30.
- the sealing body 10 is in its shape and size to the component insert 50; 60 adjusted. Based on the wire thread insert 50, therefore, the sealing body 10 preferably has a cylindrical or hollow cylindrical shape.
- conical or truncated cone-like shapes of the sealing body 10 also fulfill the sealing function explained in greater detail below. While the hollow cylindrical shape of the sealing body 10 is illustrated in FIG. 2, FIG. 3 shows a cylindrical shape and in FIGS. 4 and 6 a preferred conical shape of a sealing body 10 is shown schematically.
- the shape and size of the sealing body 10 are designed such that they the inner opening of the component insert 50; Fill 60 and seal on all sides. Therefore, the sealing body 10 is preferably at least as long as the wire thread insert 50, so that the inner opening of the wire thread insert 50 is sealable over its entire length in the radial direction and at the end faces.
- the sealing body 10 is preferably larger than the mecanicalclimesser the inner opening of the wire thread insert 50 is formed so that the radial outer walls of the sealing body 10 create a tight and sealing against the radial inner wall of the wire thread insert 5. It is preferred to form the sealing body 10 as a solid body (not shown) or with an inner opening 18. If the sealing body 10 has the inner opening 18 (cf., FIGS. 2 and 7), it is also preferable to radially expand the sealing body 10 within the wire thread insert 50. This is, for example, via a core pin and its special shape or via the injection of a medium (see FIG and 9), such as air, into the opening 18 (see below).
- a medium see FIG and 9
- the core pin 70 (see below) is made with respect to the opening 18 in the sealing body 10 with an oversize, so that the sealing body 10 is pressed radially outward against the inner wall of the wire thread insert 50 or the component insert 60. While on the one hand the core pin 70 can generate certain deformations of the sealing plug 1 and in particular of the sealing body 10 by its shape, it is also preferred to achieve certain deformations of the sealing body 10 via a shape of the inner opening 18. Therefore, the inner opening 18 is preferably cylindrical ( Figure 2), drop-shaped ( Figures 3, 9) or tapered ( Figures 4, 6), with other shapes being preferred.

- the sealing body 10 is a solid body (compare Figures 2 and 4), the component insert 50; 60 positioned and held by suitable positioning in the tool or in mold halves.
- the sealing plug 1 is positioned with component insert 50: 60 on a core pin 70 within a mold half or mold (step III). It is also preferable that the component insert 50; 60 first in the tool or a mold half to position and only then the sealing plug 1 in the component insert 50; 60 use.
- the sealing body 10 is widened by the geometry of the core pin (Scliritt IV) or by introducing a medium into the sealing body 10 (step V).
- FIG. 7 illustrates the core pin 70 without openings
- FIG. 8 shows the core pin 70 with radial openings 72
- FIG. 9 shows the core pin 70 with an axial opening 73.
- Air or another medium is preferably introduced into the sealing body via the openings 72, 73 10 introduced to widen it, preferably radially expand.
- the core pin 70 is first inserted into the sealing body 10 and thereby seals the opening 18 by its radially widened head 75.
- tissue, fibers, mats or the like are inserted into the tool in step VI and above or to the side of the construction panel insert 50; 60 layered with sealing plug 1 (step VI).
- tissue, fibers, mats or the like are inserted into the tool in step VI and above or to the side of the construction panel insert 50; 60 layered with sealing plug 1 (step VI).
- the tissues are expanded by mandrels, in order then in the expanded portions of the component insert 50; 60 with sealing plugs.
- the threaded insert 50 widens; 60 with sealing plug 1 even the later to be impregnated with curable, flowable material on tissue.
- Another embodiment is to cut in the fabric layers and then in the incised sections the component insert 50; 60 with sealing plug 1 to position. It is further preferred according to the invention to provide in the layers to be impregnated bores in which the component insert 50; 60 is positioned with sealing plug 1. According to another preferred embodiment, fabric layers are applied over the component insert 50; 60 placed with sealing plug 1, as far as these fabric layers openings for receiving the component insert 50; 60 with sealing plug 1 have.
- the tool is positioned with component inserts 50; 60 closed with sealing plugs 1 and soaking material.
- the cold resin system is now introduced into the tool in order to impregnate the tissue located therein.
- a hot resin system is introduced into the tool to impregnate the material therein.
- step VIII After completion of the curing process in step VIII, the components are removed from the mold or the mold halves.
- the sealing plugs 1 are due to their elastic see material with little effort from the fastened component insert 50; 60 removed so that now a wear-free and clean thread without resin residues within the molded component is present (step IX).
- Fig. 9 schematically illustrates a wire thread insert 50 with sealing plug 1, from which the assembly aid 30 has already been removed. Since the sealing body 10 has a hollow cylindrical shape, the sealing plug 1 can be positioned with a wire thread insert 50 on the core pin 70 in the tool. The core pin 70 expands the sealing body 10 and thereby seals the wire thread insert 50. The sealing lip 12 seals the wire thread insert 50 in the axial direction against the core pin 70.
- the fabric / fibers in the tool or the mold halves is inserted, wherein the fabric or fibers are designated by the reference numeral 80.
